CONDITIT OR CABLE CLAMP AND BRIDLE-RING.

Specification of Letters Patent. Patented J an. 11, 1921.

Original application filed January 23, 1920, Serial No. 353,623. Divided and this application filed May 7,

1920. Serial To all whom it may concern Be it known that I, HENRY W. PLn sTnn, a citizen of the United States, residing at Westfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Conduit or Cable Clamps and Bridle-Rings, of which the following is a specification, taken in connection with the accompanying drawings. I

This application is a division of mycopending application for improvement in conduit or cable clamp and bridle. ring, filed January 23, 1.920, Ser. No. 353,623.

My invention relates to the combination of a conduit or cable clamp and bridle ring, and also to a cable or conduit clamp and a bridle ring as sub-combinations of the main combination, and as articles of manufacture.

My invention further relates to a cable or conduit clamp, which can be manufactured at minimum expense and to which a bridle ring may be secured either at the original installation of the cable and conduit clamp, or at any future time when it may be desirable to support one or more runs of bridle wires.

My invention further relates to a conduit or cable clamp provided with a flange having a recess or slot to receive the shank of either a fiat bridle ring, or theshank of a wire bridle ring, which has preferably, though not necessarily, been properly bent upon itself to form a U-shaped member. Such a member serves to fill the socket or recess and prevents rattling. My invention further relates to means on the cable clamp for receiving and holding the other end of the bridle ring, whether that bridle ring be formed out of flat sheet material or out of round wire.

My invention further relates to a conduit or cable clamp which is preferably formed out of sheet metal and is provided with 00- operating surfaces to receive and hold the two ends of a bridle ring. My invention further relates to bridle rings which are used with my improved conduit andcable clamps.

While my conduit or cable clamp is preferably formed out of pressed sheet material as pressed steel, it may be formed from castings of malleable iron, brass, an alloy,

aluminum orany othermetal orit may be made out of pressed fibrous material.

My invention further relates to certain combinations, sub-combinations, articles of manufacture, and details of construction, all

of which will be more fully hereinafter described and pointed out in the claims.

Inthe figures in which I have shown one embodiment of my invention. the same reference numerals refer to similar parts in the several figures.

Figure 1 is a perspective view of mylconduitand cable clamp and a cable which it supports;

Fig. 2 isa perspective view of the conduit and cable clamp shown in Fig. 1 with the addition of a bridle ring formed from flat sheet metal; I I i Fig. 3 is a vertical section through the conduit and cable clamp shown in Fig. 2;

Fig. l is a perspective view of one form of wire bridle ring which I may employ.

In the commercial use of conduit or cable clamps it is not generally possible, at the date of the original installation, ,to ;deter mine whether or not bridle rings will "be needed to support additionalrloose strands of bridle wires. cable is supporte d on wall. or other-suitable support and it may be weeks,..months, or years later that the telephone engineers will determine that it is desirable tosupport bridle wires parallel to the cable.

By my invention my original conduit or cable clamp maybe used asa separate are ticle of manufacture or sub-combination, and then later, when the needs-of the service demand it, my bridle ring may be supported by the same conduit or cable clamp; when the complete combination would beused.

In my invention I -form my conduit or cable clamp 1 with a hook portion 2 and a base 3. Preferably, though not necessarily, this. conduitor cable clamp is formed of pressed sheet metal. Theend of the base 3 I form into a flange 4 and provideit with a recess or slot 5. Preferably this recess or slot is rectangular to receive one end of the bridle ring. When the conduit or cable clamp 1 isformed of pressed sheet material,

111 commercial practice, a-

ing screw 6 which holds the clamp and the cable 8 to the wall or other suitable support .9. I also provide the conduit or cable clamp with a hole 10 to receive the upper hook 11 of the flat bridle ring 12.

This bridle ring is preferably, though not necessarily, formed of a strip of spring sheet metal and bent as shown in Fig. 2, its upper end being bent to form the hook 11 and the lower end to form the hook 13.

Ordinarily the conduit or cable clamp 3 at first would be used simply to hold the cable 8 to the wall or other suitable support.

Whenever it becomes necessary to increase the capacity or the installation by stringing bridle wires 14, 14 this can be easily done by hooking the hook 13 of the bridle ring 12 within the slot 5 and then springing the other hook 11 into the hole or slot 10, when the bridle wires 14, 14 can be strung shown in Fig. 2. It will be noted that in this form of. my invention the hooks 18 and 11 fit snugly in the elongated slots 5 and 10, respectively, so that there is no rattling or movement between the cable clamp and the bridle ring they have once been positioned. Moreover the bridle wires 1 14: are completely inclosed and cannot work free of the bridle ring. In this form of invention the hook 11 extends up ver slightly into the dead space 15, Fig. 3, so that the hook 11 securely holds one end of the bridle ring but does not touch, out, scratch or mar the cable 8.

Should it ever bedesirable to remove the bridle wires 14, 14 this can be easily done by compressing the bridle ring 12 so'as to release the flat hook 11 from the elongated slot 10 which will then permit the hook 13 to be lifted out of the slot 5 in the flange 1.

In some cases I may use a round wire bridle ring 16 as shown in Fig. 4; This wire bridle ring 16 is bent'to form a bow 17. One end is bent up to form a hook 18 while the other end is bent back on itself to form a U-shaped hook 19 having two arms 20 and 21. In positioning the hook 19 in the elongated slot 5 in the flange at, the arms 20 and 21 preferably give slightly so that they are under some slight tension. This serves to prevent rattling of the hook 19 within the slot 5.

This wire bridle ring 16 is applied to and removed from the conduit or cable clamp?) in the same manner as the flat spring bridle ring 12 of the other figures.

It will be noted that in both forms of my improved construction no tapping or screwthreading of the conduit or cable clamp is required, nor is it necessary to place screw threads upon either of the bridle rings 'which I employ. This of course saves considerable expense in the manufacture of the article, and reduces the amount of metal necessary to make the conduit or cable clamp.

Having thus described this invention in connection with illustrative embodiments thereof, to the details of which I do not desire to be limited, what is claimed as new and what is desired to secure by Letters Patent is set forth in the appended claims.
